Be it known that I, AUGin-L, HANSEN LL I citizen of the United States, and a resident tion.

of. Evanstom in: the County of; Cook and State of Illinois have invented; certain new and useful Improvemeuts in Tufting Needles, ;of which the following is a specific&-

Thi invention rcletes ;to improvements i-n tufting'needles, and more pztcularly to needles adapted for use in embroidering and other fancy work ;involvng the' application of ornamental figures uponfabric. u

The objectiof the. inventon isto provide a. useful 'tool br: implement designedjtoj .be

used by the ,worler in. making successive perforations in the fabric, and simultaneously passing V a thread, or' yurn, thru the perforation, leaving a loopon the opposite side to be subsequently 'teated .depending on the design or-character of wojrkbeing done. A further object ofthe invention is to provide a nedle of' the character de- ;scribed which willgpermit of an ,adjustment; namely, in the length o f the penetrating 'portion of 'the 'needle, and therefore oftheiength ofthe loopfpassed thru the tab ric, such adjustment being desirable' for working upon fabrics of varying thickness.

A preferred embodiment of theinventio'n' is illustratedin the accompanying drawings, in which- Fgure l is a View in elevetion of the needle as essembled,`

Figure 2 is a detailed View in longitudinal section ofthe outer shell of the needle,

Fgure 3 is a View in elevation of the internel member consttuting the neede proper, or penetrating implement,

Figura 4 is anotherview in-elevetion of the needle proper, and

Figure 5 is a cross-sectional View taken on line 5-5 of F igure 1 The needle or complete implement comprises in general a tubular member l in the nature of :in external member formng the portion which is held in the hand of .the worker in using the same, en internal tubular member somewhat ?longer than the external member 1,' and telescoping theren, one end of said internal member being reduced in size and pointed to form a sharp. penetrating member 3, and finally, a screw collar 4 mounted at the upper end of the eX-` ternal member l, and ecting to lock the ex nal 'member or sleeve 'is A an elongetedftubur ti? e teme VTUFTINGNEEDLE., r v

As clearly shown In Figure 2, the'exter lershell having a somewhatenlerged per while in use; -At therear or. upperehd of the 'externel s1eeve l s' providede screw the screw collar i ,45 having.. its; sur-face" lmurled to permt the same to 'be morerezdscrew threeded portion the externel sleeve 'IS s'pht longtudmelly by the provisiou of a series of. kerfs ?spaced circum ferentielly ;s ton 5 intermediate its end, the. suracejof i which shnurledto prevent the implement, V from slippng n the fingers of gthe worker" ..65 threededportion 6 upon which is mounted about the screw thread'ed:endfjportion of said sleeve, thereby afiordinge certtin dea 9.'ree of flexibility for; .the urpose 'herein efter to 'be pointed out;

The, internal member orn dl mt',

is liklewise' e tubular member consitingof shenk portion 8 adapte d to snuglywitly in the externel sleeve'Land to slidelongitudinelly; theren. :Thruout the forward portion otthe shenk& asubstentel pali-toi the metal is cut away in such a manner that e a tepermg reducton s provided, ter'mnat- I ing some distance short of `the forward ex: tremty oi` the internal member; nemely, at 9, At this point, the metal 'is' bent' into substantially tubular form; providing ai' round penetratingporton 3 of considerebly reduced diameter. The extremity is beveled to provide a sharpened point, and immediately adja'cent the point is formed an eye 10. As clearly shown in Figure '3, the penetrating portion is substentielly oneha-lf the diameter of the tubular 'member' 2, and is oftset from 'the exs thereof Thruout the shanit portion 8 are provided a series of equidstantly 'spaced annular grooves ll cut in the surface of the tubular member, and serving to determine the ade justmeht of the internal membenes will now be described. The external and inter` nel members are assembled as clearly shown,

i ..Fig ra *1, the penetra'ting implement 3 Y -O U projecting from the forward end of the'externelmember, end the shank portion 8 engaging the reer end portion ofthe external i v member l. The internal member 2 is slidable within the external member, providing the screw coller 4 is unscrewed, 'thus permitting a free sliding' Inovement between the two parte. The presence of'the grooves n thesurface 'of' the internal member pro` vides a series of shoulder-like obstructions ,whichsare readily noticeable-in theslidingof the parts relative to each other, the tendi -ency being for the internal member to come to rest 'When any one of the grooves come in contact With the adjacent end of the 'ex-- ternalmember, thusconstituting an index as to the' lengthof the penetrating portion' 3 projecting from. the opposite end of the external member, In' this manner, therefore, a pre dete'rmined length of the penetrat ing portion 3 can'be readily dctermined, and the proper adjustnent {having ,been

,-inade, the screw collar 4 is screwed tightly in 'place', thus contracting the split portion 6 and lbcking'the two'parts together.

En operating'the needle or implement, the thread' or yarnis passed longitudinally thru i the" entire' length of the internal passage,

v entering fromthe rcar end' and passing thr the eye 10-. The desh-ed length having' been dete'rmined ;tomeet the 'requirements of the work, the needle is then repeatedly forced thrn the fabric a distance which is limited the forward endof the external member As before suggested, With each penetration and Withdraival of the needle of the thread or yarn, a loop is forned on the ,under side of thefabric, which 'loop remains after the needle is withdrawn. Thus ,it will'be'seen that anynumber of loops may be formed by repeatedpenetrations of the fabrc carried out in accordance with some pre-arranged design or pattern.

2. A needle of my name this Having described the construction and e advantages of the deviceembodying the invention,' I claim i l; A needle of the, character described,

comprsng two telescopie tubular members,

the 'internal member having a needle-like the internal member 'having' a needle-lkc 4 end' portion adapted to project from' one end of said external member, the opposte end of said external member being provided With a threaded and .split portion, and a looking collar mounted on said portion,

3'. A needle of the characterdescribed, comprising two telescop-ic tubular members, the internal member having a needl'e-like end portion adapted' te project ri-om one end' of said'extcrnal member; and a screw collar mounted the opposite end of said external member, the same beingsplit lengthtvise adjaeent said collar,` and said internal member provided With a series; of spaced'annular grooves acting todetermine the locking positions corresponding to the lengths of the needle end to be exposed.
